Oxidases

a group of enzymes of the oxidoreductase class. Widely distributed in nature, oxidases catalyze oxidation-reduction reactions in which molecular oxygen acts as a hydrogen acceptor in living cells. Water (H₂O) or hydrogen peroxide (H₂O₂) is formed during the transfer of hydrogen from the oxidized substrate to O2. Some oxidases are metal-containing enzymes, for example, tyrosinase and ascorbic acid oxidase contain copper; others, such as glucose oxidase, are flavoproteins.
